Question

Why can we easily observe diffraction effect for sound waves but not for light waves?

Answer 1

Answer:

Diffraction effect is more pronounced if the size of obstacle or aperture is of the order of the wavelength of the waves. As the wavelength of light( ~10−6m) is much smaller than the size of the objects around us, so diffraction of light is not easily seen. But sound waves have large wavelength.
